Capacidade preditiva dos saltos com agachamento profundo e Abalakov no desempenho do chute circular em atletas de elite de esporte de combate

Abstract

The present study investigated whether deep squat jump (DSJ) and Abalakov jump (ABK) variables correlate with rear roundhouse kick performance in elite combat sport athletes. For this, 26 elite Taekwondo athletes (12♀) performed three valid attempts for: (a) DSJ, (b) ABK (Pasco® force platforms) and (c) roundhouse kick (Vicon® Motion Systems). The main results indicated that for DSJ, the Concentric RFD-100ms independently predicted Lineal Foot Velocity (R²=0.21, p=0.009), Lineal Foot Acceleration (R²=0.303, p=0.003), and Angular Knee Acceleration (R²=0.194, p=0.021). Combined with Concentric Mean Power/BM, it predicted Angular Knee Acceleration (R²=0.27, p=0.04). For the ND limb, Takeoff Peak Force independently predicted Angular Hip Acceleration (R²=0.144, p=0.029), improving when combined with Force at Peak Force (R²=0.315, p=0.013). For ABK, Eccentric Peak Force/BM predicted Total Time (R²=0.123, p=0.039). Concentric Peak Force/BM predicted Angular Knee Velocity (R²=0.173, p=0.018). Eccentric Braking RFD-100ms (D) predicted both Angular Hip Velocity (R²=0.135, p=0.034) and Angular Hip Acceleration (R²=0.24, p=0.006).in conclusion, this study demonstrated that DSJ and ABK variables predict roundhouse kick performance. Key assessment variables include Concentric RFD-100ms and non-dominant limb Takeoff Peak Force for DSJ, as well as Eccentric Braking RFD-100ms for ABK.
